AIX 5.3 ML 03 is assumed. The gcc 4.0 or later should be installed.

Make sure you have a few tens MB of free space in the following directories:
- /usr the default place for (or where ever you want to install PHP),
- /opt where many of the pre-requisite libraries are installed and
- in the directory you use for the compile,
- some space in /tmp never hurts too.
Download the following:
- PHP 5.2.5 source code
  - From http://www.php.net/downloads.php
  - For me the file was called php-5.2.5.tar.gz, but you might be fine a later versions as well.
- XML Support - this has to be the very latest and the AIX Toolbox for Linux Application site was back level
  - From http://gnome.bullfreeware.com/new_index.html
    - libxml2-2.6.26-1.aix5.1.ppc.rpm
    - libxml2-devel-2.6.26-1.aix5.1.ppc.rpm
- General tools - all from http://www.ibm.com/servers/aix/products/aixos/linux/download.html
  1. LEX flex-2.5
  2. bizon
  3. XML support expat-1.95.7
  4. Compression library zlib-1.2.2
  5. Compression development zlib-devel-1.2.2
  6. jpeg support libjpeg-6b-6
  7. jpeg support development libjpeg-devel-6b-6
  8. png support libpng-1.2.1-6
  9. png development libpng-devel-1.2.1-6
  10. Pixmap xpm-3.4k
  11. Pixmap development xpm-devel-3.4k
  12. Freetype2 fonts freetype2-2.1.7-2
  13. Freetype2 fonts development freetype2-devel-2.1.7-2
Install all the RPM files - if they are in one directory you can use shortcut:

rpm -Uvh *.rpm
Uncompress the PHP source code file and untar the files
```
gunzip php*tar.gz
tar xvf php*.tar
```
- You should now find a sub-directory with the name of php plus the version number. In my case it was "php-5.2.5"
- cd to this directory
If complied with oracle correct file $ORAHOME/rbms/public/oratypes.h (for some mental or religious reasons) it contains these lines:

/* --- Signed/Unsigned eight-byte scalar (orasb8/oraub8) --- */

#if (__STDC__ != 1) || defined(__64BIT__)

# define ORAXB8_DEFINED

# ifndef lint

# ifdef __64BIT__

typedef unsigned long oraub8;

typedef signed long orasb8;

Correction:

1. Add

|| defined(HAVE_LONG_LONG)

to the #if

2. Before configuring php, execute

export CFLAGS="$CFLAGS -DHAVE_LONG_LONG"
Add /opt/freeware/bin to the PATH and -DHAVE_LONG_LONG to CFLAGS (if complied with Oracle)

export PATH=/opt/freeware/bin:$PATH

export CFLAGS="$CFLAGS -DHAVE_LONG_LONG"
Run the following configure script
```
./configure --prefix=/usr/local \
  --with-apxs2=/usr/local/apache2/bin/apxs \ 
  --with-config-file-path=/usr/local/apache2/conf \
  --with-gd \
  --with-ldap \
  --with-zlib-dir=/opt/freeware/lib \
  --enable-shared --disable-static \
  --with-zlib \
  --with-jpeg-dir=/opt/freeware/lib \
  --with-png-dir=/opt/freeware/lib \
  --with-xpm-dir=/opt/freeware/lib \
  --with-oci8=/oracle/app/oracle/product/10.2.0/db_1 \
  --with-freetype-dir=/opt/freeware/lib \
  --with-oci8=/oracle/app/oracle/product/10.2.0/db_1
```
Notes:
- If you get errors one of the most probably reasons is that you did not install some development libraries from the list above, for example:
  - jpeg support development libjpeg-devel-6b-6
  - png development libpng-devel-1.2.1-6
  - Compression develoment zlib-devel-1.2.2
  - Pixmap development xpm-devel-3.4k
  - Freetype2 fonts development freetype2-devel-2.1.7-2
- Explicit path to Apache dynamic library support (apxs) file, shared libraries are provided.
- Several options needed for most webservers are used,
- Additional libraries:
  - zlib for compression
  - jpeg and png for images,
  - XML support.
- ./configure --help - will show you the dozens of options.
- Configure can take a long time - like 10 minutes (go for a cup of tea)
- Database support
  - If you only want Apache and PHP then you don't need this last line --with-oci8 - simply remove it.
  - If you want Oracle you need to use the option
    --with-oci8=/oracle/app/oracle/product/10.2.0/db_1
    or
    --with-oci8=$ORAHOME
    
    if $ORAHOME is defined
  - (the path is the value of $ORAHOME). If $ORAHOME is defines in your environment you can omit the path.
Compile PHP with the following command:
```
make
```
- There will be compiler warnings about pointers type mismatches. As these were warning, I ignored them.

Compiling PHP with Oracle support

There can be the following complication if you use Oracle (see #38029 [NoF-Bgs] oci8 make procedure mistake):
In file included from /home/bezroun/php-5.2.5/ext/oci8/oci8.c:50:

/home/bezroun/php-5.2.5/ext/oci8/php_oci8_int.h:354: error: parse error before 'oraub8'

make: The error code from the last command is 1.

Error: oraub8 undeclared

Cause: $ORAHOME/rbms/public/oratypes.h (for some mental or religious reasons) contains these lines:

/* --- Signed/Unsigned eight-byte scalar (orasb8/oraub8) --- */

#if (__STDC__ != 1) || defined(__64BIT__)

# define ORAXB8_DEFINED

# ifndef lint

# ifdef __64BIT__

typedef unsigned long oraub8;

typedef signed long orasb8;

Solution:

1. Add

|| defined(HAVE_LONG_LONG)

to the #if

2. Before configuring php, execute

export CFLAGS="$CFLAGS -DHAVE_LONG_LONG"

Installation of PHP

Install PHP with the following two commands

make install

Installing PHP SAPI module: apache2handler
/usr/local/apache2/build/instdso.sh SH_LIBTOOL='/usr/local/apache2/build/libtool' libphp5.la /usr/local/apache2/modules
rm -f /usr/local/apache2/modules/libphp5.so
/usr/local/apache2/build/libtool --mode=install cp libphp5.la /usr/local/apache2/modules/
cp .libs/libphp5.a /usr/local/apache2/modules/libphp5.a
cp .libs/libphp5.lai /usr/local/apache2/modules/libphp5.la
libtool: install: warning: remember to run `libtool --finish /home/php/php-5.2.5/libs'
chmod 755 /usr/local/apache2/modules/libphp5.so
... ... ...

Install libphp5.so, if necessary and php.ini

Often make install fails to move .libs/libphp5.so to destination. In this case you need to execute the command manually:

cp .libs/libphp5.so /usr/local/apache2/modules

If you do not have your own php.ini you need to put default into conf directory

cp php.ini-recommended /usr/local/apache2/conf/php.ini

Configuring PHP with Apache2 on AIX - By Example

Assuming you have just installed Apache2+ (and it is working OK) and have just installed PHP as in the above section then this is what you need to configure PHP to work.

Stop Apache2 with: /usr/local/apache2/bin/apachectl -k stop
- Do not forget this - if you add the PHP configuration options before stopping Apache you will not be able to stop it cleanly and will have to kill it!
You will need to configure PHP into Apache2 before you use it
- Apache2 currently does not understand that PHP is an option and what to do with .php files
- In the /usr/local/apache2/conf/httpd.conf file, add the following at the end (or you can add them after similar lines in the file to keep it neat). These will let Apache know about 1) the PHP library, 2) that it should pass web server files ending with .php to PHP for processing and generating dynamic HTML and 3) that is the URL does not contain a file name (only a directory) and it finds a index.php file then it should by default open that file just like it does for index.html files.
```
LoadModule php5_module modules/libphp5.so
AddType application/x-httpd-php .php
DirectoryIndex index.php
```
- Seasoned Apache Administrators may have other approaches and config file setups, but the above will get you started.
- Edit the /usr/local/apache2/conf/php.ini file and change the line
```
;date.timezone =
```
- to
```
date.timezone = "Europe/London"
```
- or what ever time zone you are in. This helps applications that get confused when working out the Timezone in other ways.
Restart Apache2 with: /usr/local/apache2/bin/apachectl -k start
Now test PHP with Apache2
- Create a file in the web server files directory (default /usr/local/apache2/htdocs) called testing.php as the following two lines:
```
<h1> PHP testing </h1>
<?PHP phpinfo() ?>
```
- Make this file readable by everyone with:
  
  chmod 755 testing.php
- Make it owned by nobody with:
  
  chown nobody:nobody testing.php
- Now use you browser to access the file with a URL of
  - http:<you-machine>/testing.php
  - You should see a lot of PHP information - this is everything that is available to the PHP script writers and can be useful in debugging some problems.

Once compiled moving Apache2+PHP to an new/production machine

Backup the Apache2.2 and PHP files that by default are in the /usr/local/apache2 directory (assuming space for this in /tmp, its about 45MB):
```
cd /usr/local/apache2
tar cvf /tmp/apache2.tar
```
Copy or FTP this to the new machine here we assume the file is in /tmp and install them with
```
mkdir -p /usr/local/apache2
cd /usr/local/apache2
tar xvf /tmp/apache2.tar .
```
Install librariesfrom the original RPM files (as we did for compiling but you only need a subset of the libraries). The list of RPM is below and where to get them:
- XML Library Support - this has to be the very latest and the AIX Toolbox for Linux Application site was back level so from http://gnome.bullfreeware.com/new_index.html
  1. File libxml2 2.6.21 (find and use the rpm link)
- General Libraries - all from http://www.ibm.com/servers/aix/products/aixos/linux/download.html
  1. jpeg support libjpeg-6b-6
  2. png support libpng-1.2.1-6
  3. Pixmap xpm-3.4k
  4. Freetype2 fonts freetype2-2.1.7-2
  5. libgcc 4.0 make it the library for AIX 5.3

Now, you should find your apache web server ready to test and run

/usr/local/apache2/bin/apachectl -t
/usr/local/apache2/bin/apachectl -k start

Install the compiler and library

rpm -Uvh gcc-4*.rpm
rpm -Uvh libgcc-4*rpm

Compiling Apache2+ using GCC

Uncompress the Apache Web Server source into your home directory

# gunzip httpd-2*tar.gz
# tar xvf httpd-2*.tar
# cd httpd*

Build the configuration file enabling shared object

# ./configure -C --enable-so --prefix /usr/local/apache2

Compile the server

# make

Install the server (/usr/local/apache2)

# make install

Compiling PHP using GCC

Uncompress the PHP source code file and untar the file

# gunzip php*tar.gz
# tar xvf php*.tar
# cd php-5.1.4

Build the configuration file enabling shared objects

# export PATH=/opt/freeware/bin:$PATH
# ./configure --prefix=/usr/local --with-apxs2=/usr/local/apache2/bin/apxs --with-config-file-path=/usr/local/apache2/conf --with-gd --with-pear --with-gettext --with-mime-magic --with-zlib-dir=/opt/freeware/lib --enable-shared --disable-static --with-png --with-zlib --with-bz2 --with-xml --with-jpeg-dir=/opt/freeware/lib --with-png-dir=/opt/freeware/lib --with-xpm-dir=/opt/freeware/lib --with-freetype-dir=/opt/freeware/lib

Install PHP with the following two commands

# cp .libs/libphp5.so /usr/local/apache2/modules
# cp php.ini-recommended /usr/local/apache2/conf/php.ini

Configuring Apache2 with PHP

Stop Apache2

# /usr/local/apache2/bin/apachectl -k stop

Edit /usr/local/apache2/conf/httpd.conf, adding the following at the end

LoadModule php5_module modules/libphp5.so
AddType application/x-httpd-php .php
DirectoryIndex index.php

Edit the /usr/local/apache2/conf/php.ini file

Change the php variable:
;date.timezone =
to reflect your timezone

Restart Apache2

# /usr/local/apache2/bin/apachectl -k start

Now test PHP with Apache2

Create a test web page

# vi /usr/local/apache2/htdocs/phpinfo.php

<h1> PHP testing </h1>
<?PHP phpinfo() ?>

Open the page in your browser: http://your_server/phpinfo.php

Verify the php data

Delete phpinfo.php

# rm /usr/local/apache2/htdocs/phpinfo.php
